java - 尝试将 Mule 与 Drools 集成时遇到 "unqualified type in strict mode for: MessageExchangePattern"

Question

我正在尝试将 mule 与 drools 集成，我主要按照此处的教程进行操作，但出现此错误:

• (1,22) unqualified type in strict mode for: MessageExchangePattern
• (1,30) unqualified type in strict mode for: ONE_WAY '

我似乎无法找到解决方案，有人可以帮助我吗？谢谢。

这是我的 .drl 文件:

global org.mule.module.bpm.MessageService mule;

导入 com.hamgam.hit.esb.*;

rule "La Vita Ebela"
dialect "mvel"

when
    $x:XMLDTO( inputXML == "inputXML" )
then
    mule.generateMessage("emc",  "KeyValueMatched", null, MessageExchangePattern.ONE_WAY);
end

这是骡子流:

Answer 1

您需要:

import org.mule.MessageExchangePattern

否则您的 Drools MVEL 脚本将不知道 MessageExchangePattern.ONE_WAY 是什么。
